See the TM100-2 diagram at [here]. Is test point 9 behaving as expected? If always HIGH, possible problem causes include (but are not restricted to) switch and a poor P8-to-J4 connection.The error message that I am receiving is saying write protect error when I try to format a blank 360 KB floppy disk. The notch is not covered on the disk and in fact the floppy disk is a new disk. Could this be a a head issue or what?
